A veterans organization is suing the Pentagon for exposing private details about troops’ military service on “a truly massive scale” due to lax security on one of its websites.

The lawsuit filed by Vietnam Veterans of America says a Defense Department website “is currently exposing private details about the military service of millions of veterans to anybody at all, anonymously, for any purpose.”

The shoddy security measures allow virtually anyone to access sensitive data about veterans’ records by typing in a name and date of birth, which are easily available on the internet.
